done for the urpose of forming a compact structure, and at the same time, equalizing the tension on the two sections. The lugs and projections could, however, be placed in substantial alinement centrally of the sections 3 and 4.

The operation of the device will be readily understood when taken in connection with the above description. The dumb-bell is seized in the hand and squeezed by flexing the fingers. This may be accompanied by other motions of the arms if desired. The gripping of the sections 3 and 4 of the dumb-bell causes the spring 20 to stretch, thereby resisting the gripping action. This will be found to readily increase the size and agility of the muscles of the forearm if used frequently.

The tension of the spring 20. and thereby the force necessary to squeeze the sections 3 and 4 together, can be regulated by rotating the adjusting rod 22. Further, the distance of the members 3 and 4 apart can be regu- .lated for difi'erent sizes of hands by rotating the rods 24 and 25.

While I have shown and described one embodiment of my invention, I do not wish to be limited to the specific form or elements therein, but desire to be protected in various chan es and modifications I may make within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:-

1. An exercising device, comprising a plurality of relatively ad'ustable members, means for limiting the relative movement of said members, comprising nuts having angular connection with said members and screw-threaded rods adjustably connected to said nuts, toggles connecting said membc'rs,a spring connected at one end to one of said togglcs, a swivel connected to the opposite end of said spring, a screw-threaded adjusting rod connected to said swivel-and also connected to the other of said toggles, and a hand grip for said members.

2. The combination with a dumb-hell divided into a plurality of sections, of a single spring located within said dumb-hell and extending in substantially the same longitudinal direction as said dumb-bell, for holding the ections of said dumb-bell apart and adapted to yield under pressure on said sections to permit the approach of said sect-ions toward each other, and means for varying the tension on said spring.

3. The combination with a dumb-bell divided into a plurality of sections, of a plurality of spaced toggles connected to said sections, and a spring connecting said togtend to straighten said toggles so as to force said sections apart, and adapted to yield under pressure on said sections to permit the approach of said sect-ions toward each other.

5. The combination with a dumb-bell divided into a plurality of sections, of a plurality of spaced toggles connected to said sections, and a spri connecting said toggles together, normal y tending to straighten said toggles, said sprin bein fixedly secured to one of said togg es an adjustably secured to the other of said toggles, whereby the tension on said spring may be varied.

6. The combination with a dumb-bell divided into a plurality ofsections, of a plurality of spaced toggles connected to said sections, a sp'ning connected to one of said toggles, and an adjusting rod connected to the other of said toggles and to said spring, whereby the tension on said spring may be varied, said spring tending normally to straighten said to gles so as to force said sections apart, and adapted to yield under pressure on said sections to permit the approach of said sections toward each other.

7. The combination with a dumb-bell divided into a plurality of sections, of a plurality of spaced toggles connected to said sections, a spring connecting said toggles together, normally tending to straighten said toggles, so as to force said sections apart, and adapted to yield under pressure on said sections to permit the approach of HORATIO WHITINGQ lVitnesses:
